#### Description

The Jolokia plugin collects JVM metrics exposed as MBean's attributes through jolokia REST endpoint. All metrics
are collected for each server configured.

See: https://jolokia.org/

# Measurements:
Jolokia plugin produces one measure for each metric configured, adding Server's `server_name`, `server_host` and `server_port` as tags.
